Question

Thanks to your project i was able to run this container on a truenas installation and access it via RDP. Unfortunately there are a few limitations in truenas apps and its lack to provide/edit the compose file directly in the app section, i try to work around.

1. I would like to increase CPU/RAM --> solved by using an modified container
2. I really want to bridge the container network to my truenas network. Is there an argument i can hardcode into the dockerfile or at least kubernetes file?

With standard network, the container has access to the internet. If i am adding an external Interface (node interface) via truenas app config i can see that it will be applied to the container but within windows this is not the case. Also the Internet connect doesnt work anymore.

@d22b For the CPU/RAM limits, you just need to add "Container Environment Variables", see https://github.com/dockur/windows#how-do-i-increase-the-amount-of-cpu-or-ram

For the network, you can enable DHCP variable, and configure the container as seen in these screenshots:

vdsm/virtual-dsm#687 (comment)

and

vdsm/virtual-dsm#687 (comment)

if you follow the steps from that user, it should work!

Yes! This will work.

VM_NET_DEV will replace (in my case) the standard adapter. For the value, i had to put in "net1" instead of "eth0" you can have a look in the kubernetes history and it will tell you which interface are beeing added. Maybe we should add these info to the truenas installation procedure.

Thanks again for your support!

@d22b I am building a new version where it always prefers net1 and net2 over eth0 when they are available, so this step to modify VM_NET_DEV will not be necessary anymore in this new version. For the other steps, maybe you can place screenshots here to help other people using TrueNAS.

[d22b]

Yes, i will do that.

Ultimately i have two issues left: USB & GPU passtrough. I followed (and still not finished) carefully #22 but it seems more tricky especially in truenas, to pass an nvidia gpu to the container. I mean practically it work. Jellyfin, plex etc. all of them are able to consume the gpu. It is a matter of config. But step by step.

Any advises for USB passing by env. variable?

No Luck here. I tried to add those parameters to composer.yaml. But the USB Device (CDROM) are not showing up:
